INVENroR. @om ,1l/15:95' BY l ArweA/Ey United States Patcruli MOP Dora H'. Hasse, Parma, .Ollio Application August 24, 1953", Serial No. 375,981 y 1 Claim. (CIL 15-24'6) This invention relates tothe general class of mops and As more fully explained in my patent above noted, the prior clusters and wet mops were especially vconstructed rand designed for either dusting or washing; and a wet mop was not adapted for use as a duster or dust mop.

However, with the improvedcover disclosed in my prior patent, supra, it became possible to convert quite readily a wet mop into a dust mop and tto employ the same as such without the previous danger of marring the furniture by striking the metal parts of the mop thereagainst. The cover of the above patent, which made this possible, consisted of a single body of elastic rubber that is open at its forward and rearward ends and could be readily applied over the conventional form of mop holder, this cover having holding engagement therewith at its two ends.

Now it is the object of my present invention to devise a still further improved means for holding engagement of the forward end of such a cover with the forward corner portions of the mop holder and, at the same time, to reduce the ldanger of wear in these regions of the cover so as to thereby ensure more secure engagement of the cover upon the mop holder and to prolong its life of usefulness, and at the same time to provide a means for facilitating the application of the cover to and its removal from the mop holder.

Other objects will appear from the following description and claims when considered together with the accompanying drawing.

Fig. 1 is an elevation of a familiar type of mop with my present improved cover applied thereto and with part broken away;

Fig. 2 is an edge view of the same with part broken away.

Referring now to the accompanying drawing in detail, it will be observed that here there is illustrated the same form of mop holder as in my prior patent, supra, and therefore brief reference lthereto should suffice. Upon the forward end of the handle 1 there is mounted the grooved member 2 by means of the tubular portion 3. Attached to the tubular portion 3 and surrounding the handle 1 is the coil spring 4 which is pivotally connected at its other end to the clamping lever 5 which is adapted to engage about the handle 1 when in clamped position, and which has connected thereto the ends of the clamping bail 6 adapted to engage in the groove of the companion membery 2 for holding the mop material in place. This will be recognized asl an old form of mop holder, as for instance a wet mop.

As more fully explained in the above-noted patent, my cover makes it possible to convert such a wet mop into a dry mop or duster byreplacing the wet mop strands with suitable dry mop material M, as for instance rayon or other such soft material, the cover serving to prevent the metal parts of the holder from marring the furniture during the use of the mop as a duster.

lislan improvement upon, my Patent 2,122,743, 'July As in my former patent, supra, so here also this cover 7 is `made of a single body of rubber or other suitable elas'tic'rnaterial ywhich may be formed in a mold, this cover having a rearward smaller endV part 7b for snug engagement about the handle 1 and a forward larger end opening for engagement over the corresponding end of the mop holder in the region of the clamping grooved member 2. This cover will be so designed and proportioned as to have a snug fit over these two parts of the mop, the elasticity ofthe rubber being suiicient for effective application of the cover to the mop and for holding the same thereupon in an effective and dependable manner. That is to say, theengagement of the smaller end ofthe cover withI the mop handle will prevent the same from creeping forwardly and the effective engagement of' lthe larger open marginal portion of the forward end opening willv prevent the cover from displacement rearwardly, this cover being held effectively in such position at these two regions and without requiring any further means of holding engagement at any other part of the device. This cover is of decidedly fiat form and thereby permits insertion of the mop, when provided with this cover, into comparatively small spaces into which it would otherwise be impossible to place the unprotected wet mop holder without doing considerable damage to the furniture against which the metal parts of the holder would unavoidably strike during use of the same. It is to be understood, of course, that my present cover may be employed upon the same holder when employed as a wet mop and there may be realized commensurate advantage of protection to the furniture. kAs will be observed, the forward end of this cover is subjected to a large degree to the danger of striking and marring the furniture and also to the danger of accidental disengagement of the cover from the mop holder 'during actual use of the same. Therefore my present form ofcover is provided at its forward or larger end with a throat extension 7a for engagement about the dry mop material M and at its two opposite forward corner regions with the laterally extended portions 10 and 11 which terminate in the hollow knobs 12 and 13 adapted to have loose engagement over the forward end corner portions of the mop holder so as to provide airfilled shock-absorbing or cushioning means. These knobs may be recognized as having substantial extent forwardly and rearwardly as well as laterally in the direction normal thereto as well as in depth. Thus there is obtained more effective and dependable engagement -of the forward end of the mop cover with the mop material M and of the corner portions of the cover with the corresponding parts of the mop holder; and, with this provision, including the hollow corner knobs, there will result less wear of these corner portions of the cover during actualuse of the device. These hollow knobs 12 and 13 serve also the kfurther purpose of aiording a very convenient and effective means of grasping by the fingers of the user, rather by the thumb and linger of each hand of the user, for stretching these parts of the cover during application of the same to and its removal from the mop holder. Consequently my new form of cover makes possible more eici'ent and dependable servicein the use of such a device, there is precluded the damage thatis incident to the use of other such devices, and its life -of usefulness is greatly lengthened. y Also, my present form of device may be installed and removed in a very simplermanner and with increased convenience as compared with other such devices including that of my own prior patent above noted.

WhatV I claim is:

In a mop, a one-piece cover of elastic material that is` open at only its forward and rearward ends and is adapted for engagement about the entire longitudinal extent of the clamping means of the mop and having its forward end portion of a comparatively greater width' and having the edge about `the forward opening thereof adapted for resilient retaining engagement over and forwardly beyond tthe edge of the clamping" means of `the mop, said cover at the two' laterally opposite forward corner portions being odset laterally with enclosing projecting portions so as to engage about the `clamping means of the mop and having pre-formed hollow-env closing knobs protruding laterally from said projecting portions so as to be adapted for free exible engagement over and about the forward corner projections of the mop clamping means and in spaced enclosing relation thereto laterally so as to afford shock-absorbing cushions and means of manipulating engagement by the user, the rearward end portion of the cover being of comparatively reduced diameter for snug, gripping engagement about the handle of the mop, said cover being readily separable from the mop and being adapted for attachmentthereto by insertion of the handle of the mop through the larger References Cited in the file of this patent UNITED STATES PATENTS 665,632 FinielsV Jan. 8, 1901 1,906,157 Ierousek Apr. 25, 1933 2.079,36?
